@tapiomaps in presets > well, it still does not make perfect sense to me. Maps are content, like points and tracks, and such items are not currently supported by presets. Presets for overlays as mentioned by @slarti76 > ah guys, you complicate me a life

. In the case of presets, I would rather vote for something directly implemented in the "map overlay" dialog.
@flyingman_ch ,
@john_percy,
@slarti76hmm, nothing has changed in the code here. Isn't map lagging for you or any heavy active task in process (in your device, app navigation, ?)
@balloni55I already helped few people with similar problems, but I was never able to simulate it yet

.
The solution is usually the "Discard" button in the screen with the mentioned problem (top left button). Once, weather will be better here, I promise I'll try to test it more in the field.
Give it a try and let me know if it helps.
@joelocI do not directly blame Samsung here. Btw. are you using official ROM? It looks more like a problem in the app. I just do not have a single idea how this may happen. Because you are still suffering by some random crashes and app dying, it will most probably be connected to this.
Still, no other user reported these problems. Any log or description does not help here. The app is close to release so sorry, I'll have to wait two/three weeks if more people write about this. If not, I have currently no idea how to solve this issue ... and if yes, my Pixel2 is close to replacing it, so Samsung, because of many problems that Samsung devices have, is a good adept.
